tory ,to being drawn therefrom in the form.

of cylinders or sheets, and it aims to provide simple and improved means for mounting and manipulating the pots, the apparatus contemplating means for bringing the pot into position for reception of the glass to be drawn therefrom and means for effecting rotation of the used pot for draining therefrom of the remnant glass adhering to the pot cavity'.

I will now describe my invention in connection with the accompanying drawings, rso that others skilled in the art to which it appertains may understand and construct the same, it being understood, however, that the mechanism shown in the accompanying drawings is merely one embodiment of my invention, and may be varied without departing from the broad principle of the invention disclosed herein.

Figure 1 is a top plan view of apparatus embodying my invention; Fig. 2 is avertical sectional view of the same; Fig. 3 is a similar view showing' the support for the pot or pots in elevated position preparatory to turning of the support and revolution of the pots in their passage from one furnace to the other; Fig. 4 is a top plan View showing the support as being turned or rotated to transfer the pots from one furnace to the other; Fig. 5 is a side elevation partly 1n section and showing means for presenting t0 and lifting from the pot at the draining furnace, a heat retaining device or shield enveloping the bottom of the pot; Figs. 6 and 7 are respectively a detail sectional' view and top plan view of the center of support, showing means for reversing the pots in their passage from one furnace to the other; Fig. 8 is a fragment-ary perspective View of the gear carried by the trunnion of the pots; Figs."9 and l0 are respectively an end elevation and side elevation partly in section, showing gearing for rotating the support; and Figs. 11 and l2 are fragmentary top plan and elevational views respectively, showing the support bearings for the trunnions of the pots.

The preferable form of my apparatus, as shown in the drawings, is of a type in which the pots are presented to individual furnaces and the reference numerals 2 and 3 represent glass pots into which the glass is fed and from which it is drawn in the form of sheets or cylinders in the manner well known in the art.

The numerals 4 and 5 indicate two furnaces which may be circular or rect-angular in form and which have the usual refractory lining 6 inclosed by the sheet metal casing or shell y7. These furnace bodies may rest upon any suitable refractory foundation 8 and have the bottom openings 9 into which lead the gas, oil or other fuel jets l0 which are directednpwardly or straight into the combustion chambers 11 of the furnaces.

Each of the drawing pots 2 and 3, when it is presented to the furnace 4 for the drawing operation, rests upon the top of the furnace in the manner shown in Fig. 2, the heat in the furnace ch'amber 11 below the pot keeping the pot with its molten glass fed thereto preparatory to drawing, warm and in proper condition for drawing of the glass therefrom. The seat for the pot, at the top of the furnace 4, is such as to effect a seal between the under face of the pot and the furnace body as the pot rests thereon, the refractory portion of the furnace having the upwardly projecting ledge or flange 12 which prevents the heat of the combustion chamber from reaching and destroying the metallic rings 13 carried by the pots 2 and The ring 13 of each drawing pot receives and embraces or encircles the outwardly projecting or radially disposed flange-like portion 14 of the potI and constitutes means for rcvolubly mounting the pot in the table or support 15, which mounting is effected through the medium of the trunnions 16 and 17 carried by the ring 13 and which are received by the suitable split bearing 18 of the support 15. This ring 13 is preferably made in two parts for convenience of application to and removal from the pot.

A standard 19 interposed between and in diametrical alinement with the furnaces 4 and 5 has the cylindrical base 20 in which 7 operates the piston 21 xedly carried by the vertical shaft 22. The shaft 22 is rotatably journaled in the standard 19 and has the reduced end 23 to which is fixedly secured the support or table 15. Keyed,'as at 24, against rotation, to the upper sleeve-like portion 25 of the standard 19 is the vertically shiftable sleeve-like member 26 which,

' the gear faces 31 and 32 which effect rotation of the beveled gears 33 xedly carried by the pot trunnions 17 when the gears 33 are brought into mesh with the gears 31 and 32 as thetable or support 15 is caused t0 be elevated by the piston 21 and then horizontally rotated over the furnaces, asv will *be described below, for transference of the pot-s from lone furnace to the other. Also formed on the upper face 30 of the member 26 are the smooth-faced raised curved racks 34 and 35 which extend between the terminals of the gears31 and 32 and over which the flat faces 36 of the gears 33 ride when they pass from thegears 31 and 32 in the rotation of the support 15. The shaft 22 also has the lower reduced portion 36 which passes through the stuffing boxY 37 of the base face-plate 38 of the standard 19 and cylinder 20. To the lower end of the shaft section 36 is fixedly secured the beveled gear 39 which is so positioned thereon as to be brought into mesh with the beveled gear 40' carried by the horizontal shaft 41, when the support 15 is elevated by thepiston 21. The shaft 41 may be connected to any suitable source of power, for rotation thereof. This connection is preferably made through the intermediary of the mutilated-gearing arrangement 42 of such character that one revolution of the gear 43 thereof will bring about, through the gear 44, revolutions of the shaft 41, sufficient to give the vertical shaft 22 and consequently the support 15 a one-half revolution.

The numeral 45 indicates a suitableipipefor conveying compressed-air or other oper- -ating fluid to the'cylinder 19. This pipe 45 leads t'o,` and connects with, the source of supply at the suitable controlling valve 46. With the pot 2 in the position shown in Fig. 2, the molten glass may be ladled orv otherwise fed -into the pot cavity 2 preparatory to the drawing operation,- the pot and glass being kept in a warm condition favorable to drawing of the glass, by the heat in the furnace 4. After the, glass has been drawn, and it is desired to present a clean other drawing operation, the valve 46 is ,turned in such a manner as to feed the compressed air or other fluid into the cylinder 20, causing the piston carried by the shaft 22 to be forced upwardly. The upyvard travel of the piston 21 causes the shaft 22 to be shifted upwardly and the shaft in turn causes the table or support 15 carrying the drawing'pots 2 and 3, to be'elevated. This upward travel of the shaft 22 is of a distance Isufficient to cause the drawing pots to clear the tops of the furnaces 4 and 5,V

thereby enabling the support 15 to be hori Zontally rotated by the shaft 22. As stated above, the elevation of 'the shaft 22 brings the gear 39 into mesh with the gear 40 whereby rotation of the support is effected. Such rotation of the support is clearly shown in Fig. 4. As the support passes from the furnaces in such a manner as to bring the pots out of superposed position therewith, the gears 33 of the pot trunnions A17, by this horizontal travel of the support 15, are caused to sweep across the gears 31 Vand 32 ofthe member 26 which has been elevated with the support, but which is prevented froni rotating therewith, by means of the irey and key-way 24. This travel of the gears 33 over the gears 31 and 32 causes the pots 2 and 3 to revolve on their trunnions 16 and 17, the pot 2 assuming a turned-over position with the pot cavity placed downward while the pot 3 which has,

efore therotation of the support assumed this position with the cavity downward, is turned to an upright position preparatory to its positioning over the furnace 4; the pot 2, after turning downward, assuming, as the support continues to horizontally rotate, a position over furnace 5 simultaneously with the shifting of pot 3 into position over furnace 4, by reason of the fact that these two drawing pots are disposed in the support 15, in alinement wit-h the furnaces. After the pots 2 and 3 have been turned by the partial rotation of the support, with the continued rotation of the support to bring the pots into their respective positions with the furnaces, and with the passage of the gears 33 from the gears 31 and 32, the straight-faced portions 36 of the gears 33 pass to the smooth-faced racks 34 and 35 which serve in conjunction with these faces 36 to prevent further rotation of the pots -2 and 3 after theyhhave been turned in-the manner, above described.

With the release of the pressure from the cylinder 20 by turning the valve 46, the support 15 lowers, bringing the pots into seating engagement with the tops of the furnaces; the upright pot over furnace 4 and the downturned pot over furnace 5. As the downturned pot is received on top of the furnace 5 the heat of the furnace melts the drawing pot and new batch of glass for anchilled remaining glass adhering to the imanes cavity of the used pot, the melted glass lowing down the furnace wall 47, through the neck 4&8 to the suitable floor collecting passage-way 49.

It will be seen that the upper face of the refractory lining of the furnace 5 contacts with the refractory portion of the downturned pot at a point inside the pot ring 13,

thus protecting this metal ring against destructive heating by the furnace.

, During the draining of the downturned pot over furnace 5, it may loe desirable at times to conserve the heat of the pot so that when it is placed over furnace el. it will 'not require further preparatory heating. For this purpose I provide 'thedome or'shield 50, asshown in F ig. 5, made of preferably refractory material and provided with the lifting eye 5l by means of which it maybe presented to and removed from the pot. l/Vhen in position, this dome covers the upturned pot bottom and serves to prevent dissipation of the heat therefrom. Any

suitable means may be employed for bring-` ing the dome into and out of position. However, I have shown in the drawings the pneumatic jack 52 which has the arm 53 by means of which connection-between this lifting jack and dome is made through the link arrangement 54. The vertical shaft of the jack 52 is rotatably mounted so that after the dome is raised it may be shifted to one side of the furnace.

As shown in Figs. l1 and 12 the construction of the trunnion bearings 18 of the support l5 is such that the upper half 18 of each bearing may be removed and replaced from the top of the table or support, there'- by permitting of the ready removal and replacement of the pots'without disassembling the support or reaming mechanism.

ldhile I have shown the support 15' as having openings 56 in which the drawing pots are mounted to revolve, it will be apparent, without necessity of specific illustration, that such support may be greatly varied. v

, Other changes may suggest themselves to the skilled mechanic, which would not de part from .my invention and I do not therefore 'desire to limit myself to the specific form of apparatus shown; nor do I limit myself to any particular number of furnaces and pots which may be employed.

The advantages of my invention will be readily appreciated. The apparatus is small and compact and rapid and efficient in operation resulting in the expeditious drawing` of the glass. Y

Having thus described my invention, what I claim and desire toy secure .by Iletters Patent' is:
